1.45 x 10^-7 isn't in scientific notation because if it's negative, the decimal starts before the first real number, right?
Answer:
Yes, changing from 3 states to 6 states changes the median because:
- The median of the first 3 states is simply the middle-placed state of the 3 states.
- The median of 6 states is the average of the 2 middle states.
Step-by-step explanation:
Suppose the first 3 states in order are:
A, B, C.
The median of these states is simply the middle state, B.
Adding 3 new states to have:
A, B, C, D, E, F.
The median is not explicit. It is the average of the two middle states, C and D.
Average of C and D is half of the sum of C and D.
That is (C + D)/2.
Which is different from B.
So question is 'what is x. 30% of x is 60'
remember that percent means parts out of 100 so therefor
30%=30/100=3/10
so the question is
3/10 of x is 60
'of' in math means multiply
3/10 times x=60
3x/10=60
mulitply both sides by 10 to get rid of fraction
3x=600
divide both sides by 3
x=200
.. is 200
the number is 200
1/2, becuase its 50/50 she might 25/25 she will
